1.221.1.  RHBA-2009:0453: bug fix update


This update has already been released (prior to the GA of this release) as FASTRACK errata RHBA-2009:0453
Updated tcp_wrappers packages that fix a bug are now available.
The tcp_wrappers package provides small daemon programs which can monitor and filter incoming requests for systat, finger, FTP, telnet, rlogin, rsh, exec, tftp, talk and other network services. It also contains the libwrap library that adds the same filtering capabilities to programs linked against it, like sshd and more.
These updated tcp_wrappers packages fix the following bug:
  • when tcp_wrappers performed an ident query which failed, applications which used tcp_wrappers were then unable to receive SIGALRM (alarm) signals. This has been fixed by correctly restoring signal masks in this update, so that applications using tcp_wrappers are now able to receive and handle SIGALRM signals following a failed ident query.
All users of tcp_wrappers are advised to upgrade to these updated packages, which resolve this issue.
